Abstract
A fixation device for providing rotation stability to a femoral neck fracture. The device includes a bone plate having at least one opening, a compression screw housing extendable through the opening of the bone plate, a compression screw being at least partially disposed within the bore of the housing and selectively moveable through the bore, and a collapsible and expandable anchoring member coupled to the compression screw. The anchoring member is configured to transition between a collapsed condition and an expanded condition upon advancement of the anchoring member from the compression screw housing to rotationally stabilize the compression screw within a femur.
